CVE-2026-41372: OpenClaw: Trailing-dot localhost CDP hosts could bypass remote loopback protections
(updated )
Before OpenClaw 2026.4.2, remote CDP discovery could return a trailing-dot localhost host such as localhost. and bypass OpenClaw’s loopback-host normalization. That let a non-loopback remote CDP profile pivot the follow-up connection back onto localhost.
